Dichroic Beamsplitters

In many scientific and electronics applications, it is necessary to split an incident beam into two spectral bands – one transmitted, the other reflected – and maintain an extremely sharp slope of transition between the bands. These are called dichroic beamsplitters. And since they utilize dielectric materials, they carry the advantage of having negligible optical loss compared to absorptive types of color separators.

Dichroic beamsplitters and filters separate one band of light from a spectrum in either transmission or reflectance. For example, a blue dichroic in reflection will reflect the blue band (~400 to 480 nm) and transmit all wavelengths in the longer wavelength spectral region. The beamsplitters are custom made based on your unique specifications. Please contact EMF or request a quote online.
